“grep：line too long”错误信息 [英] "grep: line too long" error message

问题描述

为了在 / etc

下找到IP地址，我使用了以下语法（Dennis Williamson在超级用户的网站）

但我收到消息grep：line too long。

有人有想法

  grep -Er'\<（[0-9] { ）{3} [0-9] {1,3} \>'/ etc / 
 grep：行太长
  

解决方案

find / xargs解决方案对我无效，但导致相同的错误。

我使用 -I grep选项（忽略二进制文件）解决了这个问题。在我的情况下，文件列表中必须有一个二进制文件才能搜索到没有换行符，所以grep试图读取一个太大的巨大行。这是我对这个错误意味着什么的猜测。

当然，这可能对您不适用有一行文本文件太长。

I used the following syntax in order to find IP address under /etc

(answered by Dennis Williamson in superuser site)

but I get the message "grep: line too long".

Someone have idea how to ignore this message and why I get this?

  grep -Er '\<([0-9]{1,3}\.){3}[0-9]{1,3}\>' /etc/
  grep: line too long

解决方案

The find/xargs solution didn't work for me, but resulted in the same error.

I solved this problem by using the -I grep option (ignore binary files). In my case there must have been a binary file in the list of files to search that had no linebreaks, so grep tries to read in a gigantic line that is too big. That's my guess at what this error means.

This might not work for you of course if there's a text file with a line that is too long.
